Vue implements multi-language switching function and commonly used plug-in recommendations

Vue is a popular JavaScript framework that allows you to quickly build interactive user interfaces. In multilingual applications, in order to meet the needs of users in different countries and language environments, we need to use multilingual features to make the application easier to use. Vue provides many useful plug-ins to help implement multi-language switching functionality. In this article, we will introduce Vue’s multi-language plug-ins and how to use commonly used plug-ins.

1. Multi-language switching function

Vue-i18n is a very popular Vue plug-in that allows you to manage and switch text in different language environments. Vue-i18n can dynamically load text content based on different regions and locales, making applications easier to use.

1. Install Vue-i18n

The easiest way to install Vue-i18n is to use npm. Open the command line and enter the following instructions:

npm install vue-i18n --save

2. Create a Vue-i18n instance

In the Vue instance, you need to create a Vue-i18n instance and configure the language pack. For example:

import Vue from 'vue'
import VueI18n from 'vue-i18n'

Vue.use(VueI18n)

const messages = {
  en: {
    message: {
      hello: 'Hello World!'
    }
  },
  fr: {
    message: {
      hello: 'Bonjour le monde!'
    }
  }
}

// Create VueI18n instance with options
const i18n = new VueI18n({
  locale: 'fr', // set locale
  fallbackLocale: 'en', // set fallback locale
  messages // set locale messages
})

// Create a Vue instance with `i18n` option
new Vue({ i18n }).$mount('#app')

In this example, we have defined two language packages - English and French. We use the locale option to specify the current locale (in this example, we use French). The fallbackLocale option is used to specify a fallback language pack (in this example, we use English). You can also set other options for the Vue-i18n instance, such as silentTranslationWarns, etc.

3. Using Vue-i18n in Vue components

In Vue components, you can use Vue-i18n’s $t (translate) function to access the current localization Text content. For example:

<template>
  <div>
    {{ $t("message.hello") }}
  </div>
</template>


export default {
  name: "App",
  // ...
}

2. Recommended commonly used plug-ins

In Vue applications, there are some commonly used plug-ins that can help you implement multi-language switching functions and improve the performance and functionality of Vue. The following are several very useful Vue plug-ins:

1. Vue Router

Vue Router is the official routing manager of Vue. It helps you manage routing and navigation in Vue applications. Using Vue Router, you can create pages, manage navigation, handle dynamic routing, etc.

2. Vuex

Vuex is a state management library that helps you manage the state of your application. Vuex provides a centralized storage area to store all the state of the application, as well as a set of methods for modifying the state. By using Vuex, you can easily share state between Vue components and implement complex application logic.

3. Axios

Axios is a Promise-based HTTP client that can initiate HTTP requests and process responses. Axios can help you manage all HTTP requests in your Vue application, including getting data, sending forms, etc.

4. Moment.js

Moment.js is a very popular JavaScript library for working with dates and times. It provides many useful methods such as formatting dates, comparing dates, etc. In Vue applications, Moment.js can help you handle dates and times easily, making your application easier to use.

5. ESLint

ESLint is a JavaScript code inspection tool that helps you identify and fix problems and errors in your code. In Vue applications, ESLint can help you maintain the quality and readability of your code and ensure a consistent code style.

Summary

Vue-i18n is a popular way of Vue multi-language management. Using Vue-i18n, you can easily implement multi-language switching functionality, making your application easier to use. In addition, commonly used Vue plug-ins can help you improve Vue's performance and functionality, and simplify code management and maintenance. If you are developing a Vue application, try using Vue plugins to improve the performance and maintainability of your application.
